Numerical Investigation of Penetration Performance of Segmented Rod Projectiles with Various Connectors
In this paper, a series of numerical simulations have been conducted to investigate the penetration performance of tungsten alloy segmented rods with various connectors and different design parameters, and corresponding continuous rod penetrate into semi-infinite thick steel target at velocities from 1.5 km/s to 3.1 km/s. The SPH hydrocode of AUTODYN was used in this paper to reveal the influences of design parameters on the penetration performance of segmented-rod projectiles. A non-ideal segmented rod projectile includes not only segmented rods but also carrier tube and connectors for assembly and integrity purposes. The penetration performance of penetrator is evaluated by examining the crater depth in thick steel targets.
